Convergent continental margin volcanic source for ash beds at the Permian-Triassic boundary, South China: Constraints from trace elements and Hf-isotopesVolcanic activity around the time of the Permian-Triassic boundary (PTB) has been proposed as a trigger for the associated biocrisis. Multiple ...
boundary Creates large displacements in rock types but does not make diagnostic features like the other plate boundaries Ancient convergent boundaries create a mixture of complicated rocks called a melange These are common on the West Coast of North America Ophiolites are slices of oceanic crust that...

Partial melting of ultrahigh-pressure metamorphic rocks at convergent continental margins: Evidences, melt compositions and physical effects[J]. Geoscience Frontiers, 2018, 9(4): 1229-1242. DOI: 10.1016/j.gsf.2017.08.002 [9] Clément Ganino, Nicholas T. Arndt, Catherine Chauvel, Alexandre Jean, ...
We test the role of the advance rate (indentation rate) of the India–Eurasia convergent boundary, i.e. the Indian continental subduction zone hinge and slab (vI), relative to the rollback rate of the Western Pacific (vWP) and Sunda (vSu) subduction zones on the style and extent of cont...
Modern orogenic belts develop at convergent plate margins, where a continental margin on one plate is undercut by oceanic lithosphere of a second plate that is descending into the earth. Magma is produced in this setting by: • Partial melting of the subducting plate, including some ocean-floo...
a fixed boundary between drainage basins. For example, in response to tectonic uplift, the westward-draining Karoo River of South Africa (proto-Orange River; Extended Data Fig.4a) incised a deep channel through the Great Escarpment43at 120–110 Ma (refs. 29,43), paving the way for flu...

(Fig.1a). For each carbonatite, we calculated the shortest distancedfrom the carbonatite to each individual cratonic boundary. For each magmatic sulfide deposit, we calculated the shortest distancedfrom the deposit to the individual cratonic boundary lines and carbonatites, respectively. We used the ...
